Answer:
12
Step-by-step explanation:
13x-21=5x+75
8x=96
x=96/8=12
Answer:
x=12
Step-by-step explanation:
Since the 2 lines are parallel we can use the rules of transversals. These 2 angels are alternate side interior. This means that they are congruent and have the same measurement. Because they have the same measurement, we can set them equal to each other and solve for x.
First, set the expressions equal to each other13x-21 = 5x+75
Next, add 21 to both sides13x = 5x+96
Then, subtract 5x from both sides8x = 96
Finally, divide both sides by 8x=12

Use the point and the slope to graph cach line. Write the equation of the line.
The line passes through point (-1, 4) and has slope - 2.
Answers
Answer:
y=-2x+2
Step-by-step explanation:
We use the formula
y=mx+b, where m is the slope, b is the y intercept, and x&y are the coordinates.
We know that one point is (-1, 4)
and the slope is -2.
We are trying to find b.
In order to do that, we plug in what we know:
so,
4=-2(-1)+b
4=2+b
4-2=b
b=2
So now we go back to the original equation and use b as our value'
y=-2x+2

Hint: Draw and label a picture to see and show what is happening.
Answers
Answer:
A) -14 + 8 = 6
B) The fish is at -6 feet below the sea level after it rises 8 feet because -14 (14 feet below 0) plus the 8 feet it rises is -6 feet or 6 feet below the sea level.

what is -9/14+2/7 as a fraction in simplest form
Answers
_________
[tex] \: [/tex]
[tex] - \frac{9}{14} + \frac{2}{7} = ...[/tex]
[tex] = \frac{2}{7} - \frac{9}{14} [/tex]
[tex] = \frac{(28 - 63)}{98} [/tex]
[tex] = \frac{ -35 }{98} [/tex]
[tex] = \boxed{ \bold{ - \frac{35}{98}}} [/tex]
Answer:
5/14
Step-by-step explanation:
-9 is just 9 so that makes 9/14 - 2/7.
Multiply 7 by 2 and that makes 14, do the same with the numerator and that makes 4/14 and 9/14 - 4/14 = 5/14
